QR Code Question

I'm working on completely rebranding the company I work for. Everything from the website, trucks, business cards to the shipping boxes. I am basically creating a new brand from the ground up.

I've done this before but I have never used a QR code. My question is I see a lot of QR code generators online that are free. However when I type in the same exact web address I notice the pattern in the code is different from site to site and day to day but, the code I generated last week seems to work fine.

Do QR codes expire and is there a way to pay for one so that a year from now the QR codes on the sides of our trucks don't lead people to some strange porn site or something?

 

QR Code Question

I'm a little late to this but QR codes are static. They're like barcodes but contain a lot more binary. If you don't get the same values from the same QR code, either the code itself has degraded (e.g. smidges making areas that should be white a shade of dark gray or black) or the software used to process it isn't working. Here's a basic breakdown of what each part of the QR code is about:



And if you want to learn more about them, see Wikipedia. The only way a well-formed QR code could point to a porn site is if you use an URL-shortening service (e.g. bit.ly) and that URL it generated gets repurposed to point to a porn site. To avoid that problem, simply don't use an URL-shortening service.

OK, that will look pretty cool.
